• Abstract:
  Ramp metering, which is a regulatory but voluntary form of control, is effective for improving freeway operations. However, traffic input demand frequently exceeds the capacity of some freeway bottlenecks resulting in upstream congestion. This study discusses the use of positive ramp closure during peak periods to further reduce traffic input to the freeway from a selected ramp. The conclusions are that freeway operation is improved, while diverted motorists experience only minimum added delay. Further research is needed to establish when and what length of time a ramp should be closed.
